Urinalysis
A laboratory test that examines the physical, chemical, and microscopic properties of urine to detect conditions such as infection, kidney disease, and diabetes. It is a common, low-cost diagnostic ordered across many outpatient and surgical settings.
What is a urinalysis?
A urinalysis is a laboratory test that examines a urine sample across three dimensions: its physical appearance, such as color and clarity; its chemical content, such as glucose, protein, and blood detected by dipstick; and its microscopic components, such as cells, crystals, and bacteria.
The combination of these findings can point to a range of conditions, including urinary tract infections, kidney disease, dehydration, and diabetes. It is a quick and inexpensive test to perform.
How is urinalysis used in outpatient and surgical settings?
Because it is low-cost and broadly informative, urinalysis is one of the most commonly ordered diagnostic tests across clinics and surgical facilities. It often serves as an early screen that flags problems warranting further workup.
In an ambulatory surgery center, urinalysis can support preoperative assessment, for instance by helping detect an unsuspected infection that might affect whether a procedure proceeds as planned. As a routine lab, it also generates a discrete billable service within the encounter.
